The Lanier Community Garden was developed by Water Resources in 2009 to offer County residents a place to grow fruits and vegetables for their families, as well as to support local food banks and other charitable organizations. The land is located on the grounds of the Lanier Filter Plant near Buford. The garden was initially cleared and tilled by inmate labor, providing 40 garden plots, but has since expanded to include more than 70, 20x20 foot plots.

The community garden has an administrative board made up of gardeners who coordinate committee activities such as tilling, grounds maintenance and composting, in addition to presenting seasonally relevant educational classes, and assuring compliance with the garden rules and by-laws. There are separate sections for traditional and organic gardening. Garden plots are available for a fee on a first-come, first-served basis. A waiting list is maintained if plots are not available.
